💡Step-by-Step Strategy for These Question Types
Follow this six-step method.
💼Step 1: Study the Diagram, Table, or Flowchart
Before reading the passage, examine the structure carefully.
Look for:
- ✅Labels
- ✅Titles
- ✅Categories
- ✅Arrows (in flowcharts)
Understanding the structure helps you predict what information is missing.
💼Step 2: Identify Keywords
Each blank usually includes surrounding words that indicate the answer.
Example:
The process begins with the collection of ______.
Keyword:
collection
This helps you locate the relevant part of the passage.
💼Step 3: Predict the Type of Word Needed
Look at the grammar of the blank.
Example:
collection of ______
The missing word is likely a noun.
Understanding grammar helps narrow down possible answers.
💼Step 4: Scan the Passage
Search the passage for keywords or synonyms.
Example:
- ✅Question
- ✅Passage
- ✅collection
- ✅gathering
- ✅stage
- ✅phase
IELTS frequently uses paraphrasing, so identical wording is rare.
💼Step 5: Locate the Exact Word or Phrase
Once you find the relevant information in the passage, identify the exact word(s) that complete the blank.
Example passage sentence:
The process begins with the collection of rainwater.
Correct answer:
rainwater
💼Step 6: Check the Word Limit
Always follow the instructions carefully.
Common instructions include:
- ✅ONE WORD ONLY
- ✅NO MORE THAN TWO WORDS
- ✅NO MORE THAN THREE WORDS
Exceeding the word limit will result in zero marks.
🏅Example IELTS Diagram Completion Question
👉Passage Excerpt
The first stage of honey production involves bees collecting nectar from flowers.
👉Diagram
Step 1: Collection of ______
👉Correct Answer
nectar
Explanation:
The passage clearly states that bees collect nectar from flowers, which completes the diagram step.
⚡Common Mistakes in Diagram/Table/Flowchart Questions
Many students lose marks because of avoidable mistakes.
💼Mistake 1: Ignoring the Structure
The visual structure helps you understand the logic of the information.
For example:
- ✅Flowcharts show process steps
- ✅Tables show categories
Understanding the structure makes it easier to identify the correct answer.
💼Mistake 2: Writing Too Many Words
If the instruction says NO MORE THAN TWO WORDS, writing three words will be marked incorrect.
Always double-check the word limit.
💼Mistake 3: Matching Words Instead of Meaning
IELTS uses synonyms and paraphrasing.
Example:
- ✅Question
- ✅Passage
- ✅stage
- ✅phase
- ✅process
- ✅procedure
Focus on meaning rather than identical vocabulary.
🏅Advanced Tip: Follow the Information Flow
In many cases, the diagram or flowchart follows the same order as the passage.
Example:
Step 1 → early in the passage Step 2 → later in the passage
This helps you locate answers more quickly.
